    Unhappy Can't get JFreeChart to work

    Hi all,
    I've wasted the whole day trying to get JFreeChart to work in NetBeans, in both Windows and Linux and have completely failed. Does anyone have any experience with this? I don't care what OS gets it up and running, I just need to use it for my GUI. I followed the help pdf and read the README and followed the instructions to the letter, but the classpaths don't seem to recognised.

    Any help would be massively appreciated

    Ps. I'm not tied to NetBeans, any method would work

    Used the jar file from JKLJar File Download and it worked fine, maybe the newest one has some bugs?
    Anyway, 13 works fine for me

    Hi Igniteflow,

    Download Jfreechar from here Download JFreeChart from SourceForge.net

    once downloaded extract the file onto your desktop!,once extracted,open up netbeans -> right click on the libraries(place on left side of your netbeans project)->select add jar/folder->dialog box pops up,navigate to the lib folder of your downloaded jfreechart-1.0.13,and add them all.now all the required libraries are placed.

    Once you are done with that,try this code out!

    import javax.swing.JFrame;
    import org.jfree.chart.ChartFactory;
    import org.jfree.chart.ChartPanel;
    import org.jfree.chart.JFreeChart;
    import org.jfree.chart.plot.PiePlot3D;
    import org.jfree.data.general.DefaultPieDataset;
    import org.jfree.data.general.PieDataset;
    import org.jfree.util.Rotation;
    public class PieChart extends JFrame {
    	public PieChart(String applicationTitle, String chartTitle) {
            // This will create the dataset
            PieDataset dataset = createDataset();
            // based on the dataset we create the chart
            JFreeChart chart = createChart(dataset, chartTitle);
            // we put the chart into a panel
            ChartPanel chartPanel = new ChartPanel(chart);
            // default size
            chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));
            // add it to our application
         * Creates a sample dataset
        private  PieDataset createDataset() {
            DefaultPieDataset result = new DefaultPieDataset();
            result.setValue("Linux", 50);
            result.setValue("Mac", 20);
            result.setValue("Windows", 51);
            return result;
         * Creates a chart
        private JFreeChart createChart(PieDataset dataset, String title) {
            JFreeChart chart = ChartFactory.createPieChart3D(
                title,  				// chart title
                dataset,                // data
                true,                   // include legend
            PiePlot3D plot = (PiePlot3D) chart.getPlot();
            return chart;
    class Main
    	 public static void main(String[] args) {
    	        PieChart demo = new PieChart("Comparison", "Which operating system are you using?");

    Kind Regards,
